Armbruster Peter Affolter Address for Service: PHILLIPS ORMONDE FITZPATRICK Patent and Trade Mark Attorneys 367 Collins Street MMelbourne 3000 AUSTRALIA Invention Title: .PORTABLE HAND-HELD POWER ASSISTER DEVICE Our Ref: 321490 POF Code: 4703/154162 The following statement is a full description of this invention, including the best method of performing it known to applicant(s): 6006 6006 f) PORTABLE HAND-HELD POWER ASSISTER DEVICE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a hand-held controllable power assister device as applied to syringes adopted to delive. a liquid into a patient.
1 0 More particularly, the invention relates to a held-held controllable power injection device for delivering, by injection, x-ray contrast media into a patient prior to or during urographic or angiographic procedures.
2. Reported Developments Urography is a radiological technique wherein at least a part of the urinary tract of a mammal is rendered opaque by intravenous injection of a contrast medium or by injection into the bladder through the urethra.
Angiography is also a radiological technique wherein the arteries or veins of a mammal are outlined by injecting a radiographic medium.
In both techniques the coated vascular structures are 2 5 radiographically imaged for diagnostic purposes.
For delivery to the desired site, the contrast medium is placed in an appropriate syringe and forced through a hollow needle or a catheter in such a manner that the contrast medium enters the blood stream or 3 0 the bladder at the appropriate time and place for taking radiographic images. As contrast medium is being injected to the site to be visualized through the hollow needle or a catheter, high pressures are often encountered, sometimes as high as 1,000 psi. This requires a rather high force to be exerted on the pirton in order to deliver the content of the 3 5 syringe. Furthermore, such force is to be exerted in a constant manner for continuous and even volume delivery of the contrast medium. Early injection systems were designed for manual injection of the contrast medium by means of a hand-held glass syringe. A mechanical injection system activated by a foot switch has also been, and is still being used for most general radiographic procedures. However, this system was only rarely used for coronary angiography for the probable reason that operator control is greatly reduced and the risk of coronary artery dissection increased.
Power injectors in general have certain advantages over handoperated injectors including the following. They reduce reliance on an assistant enabling the operator to be in complete control of the injection of the contrast medium, they can deliver a precise volume, and the S pressure generated can be limited by presetting a pressure limit.
Power injectors are of three types: hydraulic, pneumatic and electric. Hydraulic injectors have an electric motor connected to a o hydraulic pump, which drives a ram connected to a syringe that contains the contrast medium. In pneumatic injectors, the source of power is compressed gas supplied by a tank or compressor. Electric injectors are powered by electric motors in which a transmission means serves to change circular motion into linear motion which then drives a ram.
While typical power injectors eliminate the physical effort required with manual injectors, they are not easy to use, are expensive :0 and the perception of instantaneous control present with manual injectors is lost because the syringe and controls for the injectors are not hand-held or not conveniently handleable during the injection process.
3 0 For example, a gas power-assister hand-held syringe does eliminate the physical effort associated with manual injection and also provides a perceived instantaneous control of the injection, however, it requires a gas system to power the syringe, such as pressurized carbon dioxide gas. The gas delivery system includes a carbon dioxide gas tank with various indicators and controls, which reduces the portability of the device, it requires valuable space in the proximity of the injection, it adds to the complexity of using the device for the intended purpose and requires periodic replacement of the gas tank.
Battery powdered injectors are also available for use in angiography and urography employing a syringe for holding a contrast medium and a plunger connected to a mechanical means to automatically deliver the contrast medium. Some of these injectors include microprocessor technology for programming rates and time delivery and have visual or audio display for ease of controlling the injection process. As these injectors become more sophisticated, the cost of making and using them increases as well as the complexity of use tends to increase the opportunities for breakdown.
The present invention is directed to a hand-held, light-weight power assister which eliminates the physical effort required with manual injectors but otherwise allows the practitioner complete human control of the injection process.
a.oe SUMMARY OF THE INVENTION The invention provides a hand-held power injection device for delivering liquid media to a mammal comprising a pistol-shaped casing, syringe receiving means in said casing, a syringe having a syringe barrel and being removably coupled with said syringe receiving means, a slideable piston in the syringe barrel, a drive motor capable of generating angular motion and operable by a user, and a lead screw rotatably coupled with said drive motor by gear means to convert angular motion of the drive motor to linear motion of the lead screw, the lead screw being coupled to said slideable piston so that linear motion of the lead screw is imparted to the slideable piston.
The power injection device of the present invention is designed to be handheld by one hand, light weight, inexpensive and to allow complete control over the process of delivering radiopaque media to the patient by the medical practitioner.
To that end, its configuration resembles a pistol the handle portion of which 15 provides for firm hold. Activating switch, having on-off- and neutral positions may be located in the handle portion to be controlled by the index finger of the practitioner. While the device need not incorporate complicated and expensive electronic components which tend to break down and are cumbersome to use, it provides electrical energy to deliver the contrast media to the patient at a constant rate of delivery and it incorporates limit switches to automatically stop the electric motor when the lead screw, which engages the piston, is in its initial or completely extended position.
In accordance with a preferred aspect of the invention, the hand-held power assister device comprises: o C)3a r O O 4 SUMMARY OF THE INVENTION The power assister device of the present invention is designe o be hand-held by one hand, light weight, inexpensive and to allo complete control over the process of delivering radiopaque media t e patient by the medical practitioner.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, power assister device 10 is shown with syringe 12 engaging said device, butterfly needle 13 attached to said syringe by luer connector 50 and battery recharger 14 is ready to engage power assister device 10 by insertion of plug 44 into receptacle 42.
When assembled together, power assister device 10 and syringe 12, along with handle 18 and trigger 20a-20b, resemble a pistol. This 1 0 configuration provides for firm hold control and convenient handleability. The power assister device 10 comprises a casing which serves as a housing and chassis for the components contained therein.
Referring to syringe 12, as shown in FIGS. 1, 2, 3 and 9, it 1 5 comprises: a syringe barrel to receive an injectable agent therein, said syringe barrel having a luer connector 50 at one end thereof serving as means for attaching butterfly needle 13 thereto, and the other end of said 'tubular body having male coupling 46 to engage female coupling 38.
Flange 52 of syringe 12 locates and fixes syringe within a complimentary 2 0 slot (not shown) in front 16 of the power assister device 10. Loading of 0 eo syringe 12 is exceptionally easy and practical, since the syringe is droploaded onto said slot without the need of any twisting or turning motion.
Positioned in said syringe barrel in a slideable relationship is piston 48 integral with male coupling 46.
As best seen in FIGS. 2, 3, 7 and 8, the casing or housing of the power assister device 10 houses a D.C. motor 22 which produces angular rotation of gear 24. Gear 24 drives gear 26 which has internal thread 28.
Linear movement of lead screw 30 is produced by preventing its rotation 3 0 and by the angular rotation of internal thread 28. A follower 32, fixed to the back end of lead screw 30, prevents rotation of the lead screw during linear movement by the engagement of peg 32a of the follower 32 rolling or sliding in slot 32 b.
8 D. C. motor 22 is powered by rechargeable batteries 40, which are located in handle 18 of power assister device 10. Trigger switch 20 a b engageably coupled to batteries 40 and D.C. motor 22 has three positions: forward drive, reverse drive and off position. Forward limit switch 36 is positioned so that lead screw follower 32 triggers the switch and stops the motor when piston 48 is in its extended position as shown in FIG. 4. Likewise, the backwards limit switch 34 is positioned so that the lead screw follower 32 triggers the switch and stops the motor 22 when piston 48 is in its engagement position as shown in FIG. 3.
The power assister device 10 is recharged by plugging recharger 14 in a standard electrical outlet and inserting plug 44 into receptacle 42 during periods in which the device is not in use.
1 5 Reference is now made to the operation of the hand-held power assister. The syringe 12 could be prefilled with an injectable liquid, such as contrast media, or the power assister device 10 could be used to fill the syringe. If not prefilled, the empty syringe 12 is loaded onto the front 16 of the device, having male coupling 46 engage female couple 38, then placing the power assister device 10 in an upright position by placing it with is flat surface 9 on top of a flat object, such as a table. The syringe ':12 is then filled with contrast media by first driving the piston 48 to its extended position within the syringe as shown in FIG. 4. A plastic tube (not shown) is attached to luer connector 50 and the contrast media is 25 syphoned into the syringe 12 by placing the opposite end of the plastic tube in a container filled with contrast media and retracting piston 48 back into its engagement position. Upon completion of the process the plastic tube is remo -ed from the luer connector 50 and a butterfly needle 13 is attached thereto. After butterfly needle 13 is attached to luer 3 0 connector 50, the upright position of power assister device 10 is maintained until the air from syringe 12 and butterfly needle 13 is purged by driving piston 48 in the forward direction. To drive piston 48 forward or in reverse trigger switch 20a 20b is provided. Trigger switch 20a 20b is positioned in handle 18 of the power assister device to control both the forward and reverse motion of the piston: pressing results in forward motion of piston 48, while pressing 20a results in reverse motion thereof. When neither 20a nor 20b trigger switch is pressed, switch automatically reverts to neutral or off position and motor 22 becomes disengaged.
In the case when the syringe 12 is prefilled with contrast media, the syringe is loaded in the same manner as above-described, then the power assister 10 is positioned in an upright position. Syringe cap (not 1 0 shown) is removed from luer connector 50 and butterfly needle 13 is attached to luer connector 50. The air is then purged from the syringe as above-described.
04 Upon purging the air from syringe 12, the power assister device 1 5 is held by the medical practitioner at handle 18 with index finger resting on trigger switch 20a 20b which is in the off position. Protective sheath (not shown) is removed from butterfly needle 13 and the same is inserted into the injection sight on the patient. The practitioner then activates motor 22 by pressing trigger switch 20b which electrically engages batteries 40 with motor 22. Motor 22 produces angular motion which is 0o converted into linear motion through gears 24 and 26 acting on lead screw 30. Lead screw 30 drives piston 48 in the barrel of syringe 12 forcing contrast media through butterfly needle into the injection sight.
Piston 48 is driven by lead screw 30 at a steady rate, while the practitioner is able to visually observe the expulsion of the contrast es 0media from syringe 12. The medical practitioner is in complete control of the injection process. Unlike with very expensive and complicated devices where electronics take complete control over the process with the exclusion of the medical practitioner, the instant power assister device 3 0 accomplishes one result: responds to the desire of the practitioner by forcing the contrast media out of syringe 12 into the patient at a steady rate of delivery. The injection process may be interrupted any time upon releasing trigger switch into neutral position. When lead screw 30 is in its completely extended position, that is, piston 48 has completely discharged contrast media from syringe 12, lead screw follower 32 triggers forward limit switch 36 to stop motor 22.
Upon completing the injecti process, butterfly needle 13 is disconnected from the patient ad screw 30 is retracted to its initial engagement position. Syringe 12 is disconnected from power assister device 10 by disengaging male coupling 46 from female coupling 38 and disengaging flange 52 from receiving slot on front portion 16 of the device As is apparent from the foregoing description, the power assister device of the present invention is extremely simple, compact, easy to hold and operate and is inexpensive. The lack of complicated electronic components virtually eliminates failures and breakdowns which plague 1 5 complicated instruments. Medical personnel have complete control during the use of the device which makes the practice of delivering contrast media to the patient a more tolerable and pleasant experience Shai..
than that associated with bulky, complicated instrumentalities.
